So what do you think? If my '08 has no mods would I benefit from a tune?

If you have an A6, perhaps. M6? I would say you would not benefit at all.

You have an '08 so I am pretty sure that it is still under warranty. If you tune the ECM/TCM you are running the risk of jeopordizing your warranty (if that is important to you).

You can always benefit from a custom tune. There is always room for improvement and tuning to your personal driving style. I have improved several vehicals that are stock. Customers always very happy. Expecially with auto trans!
